This invention relates to a gas treating apparatus.

The object of the invention is the production of an apparatus, to practically separate 5 the harmless ingredients from the harmful ingredients in the exhaust gases of internal combustion engines, such as those used for automobiles. The second object of the invention comprises means to separate the harmless ingredients in the exhaust gases of internal combustion engines and which for the most part consist of carbon particles and foreign matter, from the harmful portion of the mixture, by means of mechanical separation and conducting the said harmful portion to the carburetter of the engine for reuse. The third object of the invention is the production of means and steps whereby the lighter combustible and harmful ingredients of the exhaust gases of internal combustion engines are automatically separated therefrom.

The fourth object of the invention is to provide means to decrease the noise of the exhaust of internal combustion en 'nes as it enters the mufller thereof. The fth object of the invention comprises means and steps to decrease the injurious effects of the monoxide gas which is discharged from automobile en- 30 gines. The sixth object of the invention is the production of means to prevent the back fire in an internal combustion engine, and to eliminate the odors of the exhaust.

In the accompanying drawings Fig. 1 represents a section on the line 1, 1 of Fig. 2 of a gas treating apparatus exemplifying the 1nvention; Fig. 2 shows a top plan view of Fig. 1 partly broken away and Fig. 3 1s a section of Fig. 1 on the line 3, 3.

The apparatus in this instance comprises the inclined housing designated in its entirety by the numeral 15, and is indicated as having the converging sidewalls 16 with the notches 17, the front connection 18 and the rear connection 20 having the nozzle 21. The front connection 18 has extendin therefrom the inlet nozzle 26 for the piping 2 extendin from the exhaust manifold, not shown, 0 the engine with which the apparatus is used.

50 The top face of the housing is recessedas indicated at 28. Piping 29 extends from the nozzle 21 and leads to the carburettorof said engine. The cover for the said housing 15 is designated in its entirety by-the numeral 30. The said cover comprises the annular frame having the converging side members 31, the front member 32 and the rear member 33. The members 31, 32 and 33 are recessed to fit into the recess 28. The members 31 have extending therefrom the side walls 34. An upper zigzag baflle plate designated in its entirety by the numeral 35 extends downwardly from the cover 30. The bafiie plate 35 comprises the legs 36' practically at right angles to the plane of the cover and the inclosed legs 37.

The upper peak ends of the zigzag baflie plate are indicated at 38 and the lower peak ends are shown at 39. The side ends of the members of the bafile plate are'shown at 40 and 41. The ends 40 and 41 are bedded in the walls 34 and the peak ends 38 are bedded in the side members 31 of the frame of the cover 30. When the cover 30 is cast the bafiie plate 35 is placed in the mould to secure the peak ends 38 and the ends 40 and 41 in place.

A lower zigzag baffle plate is designated in its entirety by the numeral 45, and comprises the legs 46 parallel to the legs 36, and the legs 47 parallel to the legs 37. At one end of the baflie plate 45 is indicated the forward longitudinal leg 48 which is bedded into the front connection 18 as indicated at 49. At the other end of the baflle plate 45 is shown the rearwardv longitudinal leg 50 which is bedded into the connection 20 as shown at 51. The upper peak ends of the baflie plate 45 are indicated at 52 and at the lower peak ends of the bafile plate 45 are formed separator openings 53. The side ends of the legs 46 and 47 are bedded in the side walls 16 of the housing 15 as indicated at 55. A zigzag passage 56 is formed between the bal'He plates 35 and 45.

A discharge chamber designated in its entirety by the numeral 60 extends from and below the housing 15. The said discharge chamber comprises the to wall 61 having the side ends 62 which are edded in no her 60.

the side walls 16 of the housing 15. The rear end of the top wall 61 is bedded in the connection 20. The forward end 63 of the top wall 61 is spaced from the connection 18 by being bent on itself to form the opening 65. The said bent over portion joins with the front wall 66 having the opening 67. To the top wall 61 is connected the curved bottom wall 70 having the side walls 71 with the flanges 72. the walls 16. The said bottom and side walls have formed therewith the curved nose 73 which terminates in the connection 18. The rear end of the discharge chamber 60 has formed therewith the rear wall 78 having the opening 79 constituting a second outlet. A mufiler pipe 80 is indicated with the outwardly extending end flange 81 and the inwardly extending flange 82. The flange 81 is fastened tothe wall 78. An, annulus 83 of crucible graphite is located in the pipe 80.

An' inclined baffie plate- 84 extends from .the top wall 61 and at its lower end is spaced from the wall 70 to .form the opening 85. A second inclined bafile plate 86 extends from the wall 61 and is spaced from the wall 70 to form the opening 87 A baflie plate 88 extends from the wall 70 and is spaced from the wall 61 to form the opening 89. It is to be noted that said bafile plates 84, 86 and 88 extend the full width of the discharge chain'- To detachabl secure the cover 30 to the housing 15 a p urality of snap connections are provided. Each snap connection comprises 'a U-shaped member having the'horizontal portion 90 and the depending legs 91 with the hook ends 92 coacting with the notches 17. A pair of curved sprmgs 93 are positioned below the portion 90 and have each one end fastened thereto by the rivets 94. A pair of latches 95 each having an arm 96 are pivoted to portion 90. Each of said latches coacts with one of the springs 93.

Straps 97 and 98 engage the apparatus to connect it to the vehicle for which it is used.

To use the gas treating apparatus the exhaust from the exhaust manifold of the engine flows into the pipe 27 in the direction of the arrow A and enters the housing 15, wherein it flows through the zigzag passage 56. While the gases are passin therethrough they are deflected by stri ing the legs 36, 37, 46 and 47 of the zigzag battle plates. Thereby the heavy portions of the mixture, which comprise carbon particles and foreign matter, drop through the openings 53, and flow downwardly in the direction of the arrow B until they reach the opening 65 when they descend and enter the chamber 60. The openings 53 are positioned below the bottom turning points of the direction of the flow of the gases in the zigzag passage 56. The carbon particles in the gases The latter are also bedded in at these lower turning points of the flow of gases in the zigzag passage 56 automatically ravitate through the openings 53. The eavy particles with'a portion of the ases then flow in. the direction of the arrow ('J and impinge against the baflle plates 84, 88 and 86;-

The latter bafile plates provide a check for the gases from flowing t rough the chamber 60. The heavy unharmful particles next enter the mufller pipe in the usual man- ,ner. The crucible graphite 83 in the pipe 80 diminishes the noise of the exhaust gases when they are discharged from said pipe 80.

The light and harmful gases of the mixture flow from the zigzag passage 56 through the rear connection 20 and enter the Having described my invention what I desire to secure by Letters Patent and claim is:
